IPC: H03K19/21
Filed: 1990-10-24
Abstract: PURPOSE:To realize comparing circuits, to which the order can be given in the same manner as a comparing circuit for all bits of one data, with a small- scale constitution by collating serial input data with one bit as the unit in order from the most significant bit and holding and comparing only the required number of bits of noncoincidance. CONSTITUTION:Inputted serial data 101 to 103 are sent to a noncoincidance detecting circuit 1, a maximum/minimum detecting circuit 2, and latch circuits 4, 5, and 6. The noncoincidance detecting circuit 1 compares and collates inputted serial data with one bit as the unit; and in the case of noncoincidance of data, this noncoincidance is detected to output a prescribed noncoincidance detection signal. The maximum/minimum detecting circuit 2 compares and collates inputted serial data with one bit as the unit to detect maximum or minimum data from comparison object data and removes data, which is detected as maximum or minimum data once, from the object of following bit collation and repeats this operation. Thus, comparing circuits to which the order can be given in the same manner as the comparing circuit for all bits of one data are realized with the small-scale constitution.
